Progress and the future for tilapia farming and seed production in Bangladesh

Tilapia farming has great potential in Bangladesh. Tilapia promises to become a primary cultured species for freshwater and brackish water ecosystems, and therefore may also be a major source of employment. Bangladesh could become one of the leading Asian countries for tilapia seed production and grow-out farming. This article looks at the current status of Tilapia farming and seed production in Bangladesh.

Value chain analysis of the aquaculture feed sector in Egypt

This study was carried out to evaluate the value chain performance of the aquaculture feed sector in Egypt, in terms of value addition, employment and profitability. The strengths and weaknesses of each link of the value chain were assessed and appropriate upgrading, management and development strategies were suggested. Quantitative data were collected for each link in the value-chain through structured questionnaires that were drafted and distributed to the key players in the sector; 25 fish feed mills and 34 fish farms covering different geographical and production regions.

Training Manual on improved carp/carp-shing poly culture in pond and dyke cropping

Due to inadequate technical knowledge and training in advanced methods of gradually growing carp poly culture, framers are not getting expected yield. From the very beginning of the CSISA-BD project, WoldFish Center has taken initiative to introduce advanced methods in carp poly culture. To do this, the shortage of skilled trainers and training materials, has, particularly, been realized. Presently, a number of manuals on carp poly culture from Department of Fisheries, Bangladesh Fisheries Research Institute, WorldFish Center and different GOs and NGOs are available.

The role of Spirulina platensis (Arthrospira platensis) in growth and immunity of Nile Tilapia (Oreochromis niloticus) and its resistance to bacterial infection

The current study was designed to optimize the dietary levels of Spirulina platensis in Oreochromis niloticus; this was tested via graded levels. Six isonitrogenous and isocaloric rations containing graded levels of dried spirulina 0, 5, 7.5, 10, 15 and 20 g/kg diet were fed separately to six equal groups of O. niloticus fingerlings for 3 months. Growth performance, non-specific immune parameters, tissue reactions and resistance of tilapias post challenge infection with Pseudomonas fluorescens were estimated monthly.

Rice-fish culture demonstration in Surin Province, Thailand

A brief account is given of project activities conducted regarding promotion of rice-cum-fish culture in Surin Province,Thailand as a means of increasing protein consumption and also income for rural people. The effect of stocking rate and stocking size on production was investigated. Three fish species were used: Cyprinus carpio, Puntius gonionotus and Oreochromis niloticus . It is believed that further research is warranted regarding rice-fish systems in which wild and cultured species can co-exist.
